Yeah, that's the dilemma we're facing. I'll be very surprised if the next Japanese pair isn't Fuji/Niou, but can't know for sure until next month.The thing is that if we make predictions now, it'll be without knowing the characters and it'll be hard to guess the score from that.
If we don't make the discussion now though, we'll get more information on the match and it'll be "unfair" on that.
Maybe we should make predictions now based on assumptions and if only a bit of the match is shown next time, we can leave the round open throughout January? That's the best compromise I can think of.
